ABSTRACT
Reflectivity is the amount of transmitted power returned to the radar receiver. The reflectivity is proportional to the number and the size of the stones in a volume unit. This means that stone size is linearly with radar reflectivity. This paper discusses the application of Doppler radar as the possibility of fragmentation material measurements during the blasting and the direct possibility of its further use in building other construction such as road embankments where grain size plays a decisive role. With this refinement, it is possible to omit additional crushing of the material, which is associated with financial costs. Effective use of residual material, as well as mitigation of environmental impact by associated technologies, would be achieved.
